TRITURATOR.

SPECIFICATION forming part of Letters Patent No. 313,906, dated March 17, 1885.

Application filed January 16, 1875.

To @ZZ whom it may concern:

Be it known that I, LEWIS H. WITTE, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a new and useful Triturator, of which the following is a specification.

My invention relates to an improvement in triturators, one object of the same being to provide a revolving mortar which may be readily adjusted and removed from its support. A further object is to provide a pestle which shall have an oscillatory swaying and vertical motion in the mortar, and which may be readily adjusted in different vertical positions in its support and removed from the support. A further object is to provideimproved devices for securing the mortar and pestle to their respective supports, and improved means for operating the same.

With these ends in view my invention consists in certain features of construction and combinations of parts, as will be described hereinafter, and pointed out in the claims.

In the accompanying drawings, Figure l is a top plan View of my machine; Fig. 2, aside elevation of same, and Fig. 6 is a modification. Figs. 4 and 5 are detached views of Fig. 6. Figs. 7 and 8 are a side elevation and top plan view, respectively, of a second modification; and Figs, 9 and 3 are top plan views of a third and fourth modification, respectively.

The posts D and E, the standard H, and a bed-plate to which th ey are attached, the guidebar K, the bracket G, and the foundation A, constitute the frame-work of the machine. The posts D and E and the standard H are conveniently in a line with each other, and are attached perpendicularly to the bed-plate. The guide-bar K and the bracket G are attached to the standard H, and are preferably parallel with the bed-plate. The posts D and E andthe bracket G are each perforated-the rst to form a bearing for the journal of the mortar-support, and the two latter to `form bearings for the operating-shaft F. The guidebar K, which projects over E and toward D, is provided 'with an elongated slot, k, the purpose of which will hereinafter appear. The shaft F is provided at its upper end with a crank, I, and at the top of post Ewith abandpu1ley,f. The shaft F is revolved by power applied t0 it beneath the bed-plate or door of the machine in any suitable manner. The crank I is connected with the pestle M by an operating-arm consisting, preferably, of the three sections J, J, and L.` The section J is provided with an upward-projecting stud or pin, a, which is adapted to be received, rotate, and slide in the slot k, and is secured in said slot by means of a nut or other suitable device fitted to its upper end. The .section J is further provided with a longitudinal channel or groove on its under side,in which the section J is adapted to slide, and to be secured in any required longitudinal adjustment by a set-screw passing through an elongated slot in the section J and engaging a threaded perforation in the section J as shown in dotted lines in Fig. 2. The end of the section J not in contact with the groove in the section J is pivotally secured to the crank-arm on the operating-shaft. The section L, or pestle-arm, is hinged or pivoted at P at one end to the section J, in such a manner as to admit of a free vertical vibratory movement, and is provided at its other end with a grooved liange or projection and threaded perforation on either side of the groove. The groove is adapted to partically embrace the pestle, and thus form a 'fi'rm' contact. A cap, N, provided with a central groove and perforation on either side of the groove, is adapted to partially embrace the pestle, and by means of thumb screws passing through the perforations in the cap and engaging the threaded perforations in the end of section L serves to clamp the pestle in any required vertical adjustment.

The above-described means for holding the pestle in the required adjustment is one of several convenient devices for this purpose, and hence I do not wish to be understood as limiting myself strictly to this or any particular construction. The longitudinal adjustability of the arm supporting the pestle enables me to adapt the position of the pestle to the proper distance from the crank.

O represents a revolving support adapted to receive the mortarB and any necessary or convenient fastening devices to hold the mortar in position.

My preferred mode of constructing, mounting, and rotating the support O is to provide IOO a circular metal plate with radial slots a, to l the upper' end of the guide K and passing hold the requisite fastening devices, and to further provide the circular plate at its center with a `journal or shaft, a4, which is adapted to revolve in bearings in the post D, and to further provide said plate at its periphery with a face adapted to receive a belt, O, passing from it to and around the pulleyf on the shaft F. Through the series of radial slots a I pass hooks c. which project over the upper rim of the mortar, and by means of adjusting nuts on the lower ends of the hooks serve to hold the mortarsnugly down on the support C.

d representsa series of stops projecting above the surface of the support C, and lying in contact with the outer surface of the mortar,

e therebyA preventing the mortar from shifting about in its support. These stops preferably pass through aseries of radial slots, a, in the plate C, and are adjustable therein, thus accommodating themselves to different sizes of mortars, and allowing of the mortar being adjusted laterally on the plate O.

The mortar B, removably secured on theV plate C, as described, is adapted to hold and retain material which is in the course of being continuously triturated.

M is a pestle adapted to triturate material contained within the mortar B. The bottom or lower end is rounded to facilitate the introduction between the pestle and mortar of material to be triturated, and thus increase the triturating capacity and preventtheactual contact of the pestle with the mortar. rlhe mortar-support pulley should be a little more or a little less than three times or four times larger than pulley f, and the pestle-arm should be of such length that at the end of the forward stroke the pestle willbe in the center of the mortar. The pestle will then constantly describe apath in a different position on or near the interior surface of the mortar, and this is the object of revolving the mortar in conjunction with the oscillating of the pestle and making the numerical measure of the circumference of the support C prime to that of the circumference off. The mortar is preferably inclined and the pestle caused to travel in a path between the center of the mortar and the lower side of it, as the inclining ofthe mortar increases its mixing power. The mortar is conveniently inclined by attaching the bedplate to an inclined support.

The construction of my machine is very susceptible to modifications. For example, the belt O, with the driving pulleyf and its driven pulley C, may be below the bed-plate, the standard H may be between the posts D and E, and the guide-bar K may be below the pestle-arm.

In Figs. 4, 5, and 6 I show, respectively, a front, top,'and side View of a verticalvibrating pestle-arm guide, and in Fig. 3 atop view of a laterally-vibrating one, the vertical vibrating guide, as shown, being hinged to the bed-plate and connected with the pestle-arm by a T-pin, S, the T-pin being journaled in crank, I', acts as a guide.

through a perforation in the pestle-arm,there by allowing the pestle arm a vertical and transverse rocking motion. The laterallyvibrating guide K is pivoted at Pto anysuitable supporting-piece.

Fig. 7 is a side View, and Figs. 8 and 9 top views, of modications, in which a second In Figs. 7 and 8 two shafts, F and F', are supported by the arm G, and provided at their upper ends with cranks. The two cranks are connected by the link J, and the pestle is connected to the link by the pitman L. The outer end of the pitman L is bifurcated, and is pivotally secured to the opposite sides by the clamp U, whichlatter is removably scoured to the pestle. The shafts F and F are situated in a line with standard H and. post D, and are operated by pinions, as shown. The pestle is guided in its movement by the arm It, hinged at one end to the upper end of standard, and connected to the pestle by the coupling T, which latter is similar to the coupling or clamp U.

In Fig. 9, instead of arranging the shafts F F with their cranks I Iin line between the standard II and post D, they are arranged at an angle with the mortar. Each shaft is supported by an independent arm, G, and two cranks are connected by the link J. The pitman L in this instance is at right angles to the link.

The pestle-arm may be in one piece, as shown in Fig. 3, and the crank I may be replaced by a cam or eccentric.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
